'OK Google' voice commands are now available inside apps and from the lockscreen

"OK Google." The phrase is slowly working its way across Google's mobile and web services, but the touchless control is about to get even better for many Android users. Previously limited to just the homescreen on Android 4.4 KitKat devices and anywhere on the Moto X (thanks to its always-on listening chip), the voice-activated command will soon be enabled on any screen, including the lockscreen, on your smartphone or tablet. That's not all, either: Google's also including a new Audio History feature that learns the sound of your voice to increase the accuracy of your searches.

The features come as part of an update to the Google Search app, which is currently rolling out slowly to devices following Google's I/O keynote. Google is making the feature available on a phone-by-phone basis, meaning that even if you are able to grab the relevant app file, you still might not be able to use it. If you are eligible, however, all you have to do is navigate to your Google Now settings and enable the options inside the "OK Google Detection" menu.
